Application filed December 29, 1914. Serial Nb. 879,547.

To all whom it-may concern:

Be it known that I, EDWARD a citizen of the United States, residing at Goldroad, in the county of Mohave and State of Arizona, have invented certain new and useful-Improvements in Carbureters;

andI do hereby declare the following'to be a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to make and use the same. This invention has for its object to provide a carbureter of improved and simplified construction embodying asprayer nozzle with the wall of the mixing chamber to control the flow of air thereto.

'Another object is the provision of a car-- bureter embodying a vertically movable sprayer nozzle carrying a hollow stem exinto a fuel reservoir and adapted. to plug or valve arranged in the reservoir to control the flow of fluid through Ii a. suitable "tral apr ture 21.

the stem. With these ard other objects in View, the invention consists in the novel construction, arrangement and formation of partsfas will be hereinafter specifically described, claimed N .and illustrated in the accompanying drawings,.in which the figure represents a vertical sectional view through the carbureter, partly broken away.

Referring to the numeral 5 indicates the hollow body of the carbureter forming the mixing chamber 6 supporting the constant level fuel reservoir 8. The constant level reservoir 8 is connected with the fuel reservoir 18 by a fuel pipe 19 and the reservoir 18 is formed integral with the lower part 20 of the body of the carbureter, which upper'end 21 into the lower open end of the upper body part 5. The part 20 is formed above the reservoir-18 with a plurality of openings 22, and the upper portion 20 of the lowerpart is separated from the reservoir 18 by a partition 23 having a cen The lower end of the reservoir 18 is formed with a threaded opening 25 receiving a plug 26 having a reduced and tapered upper end 27 constituting a valve, as will he hereinafter described.

The hollow stem 28 of a nozzle 29 is slidably mounted through the aperture 2% and packing ring 30 is threaded upon an upstanding flange 31 carried by the par- H. Drcxrn,

adapted to cooperate drawing in detail, the

her 6. through the passage suitable is threaded at its tition 23 to prevent the escape of fuel.be- I tween the stem-28 and the wall of the open-.

'ing 24. The bore'or passage 33'throug'h the stem 28' and nozz'le29 communicates with the mixing chamber 6" and the fuel reservoir 18, and the nozzle 29 is'formed with a hollow substantially conical enlargement 34: adapted to cooperate with the seat 35- formed in the lower end of the upper part 5 to control the flow of air from the lower part 20 to the. =m1x1ng chamber 6.

The stem 28 carries *a pair of diametrically opposed pins 36 slidably received within the bifurcated ends of a lever 37 pivotally supported at 38 on the lower body part 20. The upper end of the upper part 5 is connected with an elbow 39 adapted to-be' connected with the intake or intake manifold of a gas engine and 1s preferably provided with a throttle valve 40 operable-by a throttle lever (not shown).

The upper body part 5 is provided witha lateral enlargement 42 adjacent the exten sion 7 and formed with a circularbor'e143 receiving a rotary valve'44 having-an an--= ular port 45 therethrough. The bore 43 of the enlargement mixing chamber 6 through a passage 16, and the outer portion of the wall of'the bore 42 is formed with an air port 47. The rotary valve 44 is operable by a lever 48 secured to a concentric extension 49 carried by said valve.

In use, liquid fuel is conducted from the bowl 8 to the reservoir 18 through a fuel pipe (not shown) and enters the mixing cham- 28 and nozzle 29. Thequantity of air enteringthe chamber 6 for mixture with the fuel sprayed from the nozzle 29 may be varied by adjusting the lever 37 which moves the nozzle 29 thereof relative to the. seat 35 and thus increases or decreases the space between these elements. In starting an internal combustion engine. as is well known. it is desirable by introducing fuel d1 to prime the same rectlyto the cylinders thereof, and this may be accomplished with my carbureter communicates' with. the

33 in the StQ1l1" and enlargement 3 1 (not gaging the lower end of the stem upon' the tapered upper extremity- 27 of the plug 26, thus closing the, passage 33 and preventing the flow of fuel through the stem.- When the stem- 28 is in its lowermost position and the bore-or passage 33 thereof is closed by-the tapered extremity 27 of the plug 26 the env .largement is spaced a considerable distance from its seat 35, thus admitting an increase in the quantity of air admitted to the engine. The valve ll is designed for ad;

mitting an additionalair supply during the operation of the motor and. is commonly known as an auxiliary air valve. lVhat I claim is: -l. A' carburetor comprising upper and lower parts, said upper partihaving a mixing chamber and the lower part havingaairinlets therein, a fuel reservoir carried by thelower part, a'nozzle movable in said mixing chamber, a stem carried by said nozzle extending into said reservoir and having a longitudial passagtherethrough, and means arranged in said fuel reservoir adapted to be engaged by said stem to close the passage through the latter. I a

'2. A carburetor comprising 7 upper and lower parts, said upper part having a mixing chamberand the lower part having air inlet ppenings therein, a. fuel reservoir formed integral with the lower part and separated from the latter by an apertured partition, a nozzle movably mounted in the upper part, a stem projecting through said apertured partition and having a longitudinal passage therethrough, and a plug arranged in said fuel reservoir adapted to engage in said passage to close the latter.

3. A. carbureter comprising a hollow body having am'ixing chamber in the upper portion and a plurallty of a1r inlet openings in "the lower portion thereof, a fuel reservoir formed integral withlthe lower portion of said body. an apertured partition separating said fuel reservoir from said body. a nozzle inovably mounted in said mixing chamber and having a substantially conical enlargement adapted to co'iperatewith the wall of said mixing chamber to control the flow of air from said inlet openings to said mixing chamber, a hollow stem carried by said nozzle communicating the latter with said reservoir, means for ad usting said nozzle, and means arranged 1n sald fuel fuel reservoir, the lower-end of the boreof' reservoir adapted to engage within the lower extremity of the hereof close thedatter.

4. A carbureter comprising a hollow bony having a mixing chamber in the upper porthe hollow stem totion thereof and a plurality of air'inlet openings in the lower portion thereof, a fuel reservoir carried by the lower portion of said'body having an apertu e in the lower end thereof, a plug remova ly positioned inthe lower end of said reservoir and having a tapered extension projecting inwardly of saidreservoir, a nozzle movably mounted in said mixing chamber having a substantially conical enlargement adapted to. 00-

operate with the wall of said mixing chlamher to control the'flow of air from said air inlet openings to said mixing chamber, a

hollow stem formed integral with saidnozzle and communicating the-latter with said said hollow stem being flared and adapted .to codperate with the tapered extension of 1 to codperate with thewall' of said m;'xing chamber to control the flow of air from said vair inlet openings to said mixingchamiier,

a hollow integral extension carried by said nozzle and pro ectmg downwardly tl efrom, a fuel reservoir in the lower pc orof said bodv receiving thelower extremity of said hollow extension. a valve in said reservoir adapted to codperate with the lower extremity of said hollow stem to control the flow of fuel therethroiigh, and; means for adjusting said-nozzle vertically.

In testimony whereof I athx my signature in presence of two witnesses.v

EDWARD HALE DICKIE.
